摘要: 水润滑轴承作为关键的传动部件,其运行状态的稳定性对船舶的安全和效率至关重要。针对船舶水润滑轴承在运行过程中可能发生故障且单一信号诊断结果不可靠等问题,提出了一种综合利用动力学信息和摩擦学信息的Transformer-1D CNN模型,该模型通过自注意力机制有效捕捉长距离依赖关系,结合卷积网络的局部特征提取能力,能够对多种传感器数据(如摩擦系数、温度、振动信号等)进行综合分析,并结合迁移学习提出了一种跨工况的状态辨识方法,在高性能水润滑轴承综合试验台上进行试验获取数据。试验结果表明,在固定工况下的状态辨识任务中,所提出模型在测试集的准确率达99.97%;在跨工况的辨识任务中,基于特征的迁移学习方法结果优于基于参数的迁移学习方法,在三种跨工况辨识任务中准确率分别达到94.91%、91.38%、96.96%,相比于未使用迁移学习准确率分别提升了17.43%、18.03%、13.59%,证明了所提出的Transformer-1D CNN模型及其结合迁移学习的方法在提高船舶水润滑轴承故障诊断准确性方面的有效性,能够为船舶运营安全提供可靠保障。

Abstract: As a critical transmission component,the operational stability of water-lubricated bearings is essential for the safety and efficiency of ships. To address the potential failures of ship water-lubricated bearings during operation and the unreliability of diagnostic results based on single signals, this study proposes a Transformer-1D CNN model that integrates dynamic and tribological information. The model leverages the self-attention mechanism to effectively capture long-range dependencies and combines the local feature extraction capabilities of convolutional networks. It enables comprehensive analysis of multi-sensor data, such as friction coefficient, temperature, and vibration signals. Additionally, a cross-condition state identification method based on transfer learning is introduced. Experimental data are obtained from a high-performance water-lubricated bearing comprehensive testing platform. The results show that for state identification tasks under fixed conditions, the proposed model achieves an accuracy of 99.97% on the test set. For cross-condition identification tasks, the feature-based transfer learning approach outperforms the parameter-based method,achieving accuracies of 94.91%, 91.38%, and 96.96% in three cross-condition tasks, representing improvements of 17.43%, 18.03%, and 13.59%, respectively, compared to non-transfer learning methods. These findings demonstrate the effectiveness of the proposed Transformer-1D CNN model and its integration with transfer learning in enhancing the accuracy of fault diagnosis for ship water-lubricated bearings, providing a reliable safeguard for ship operational safety.
